LENS POLISHER.-

Application filed September 18, 1922. Serial No. 588,908

To all whom it may concern:

Be it' known that I, HARRY W.- Hum, a

citizen of the United States, residing at Southbridge, in the count of Worcester and State of Massachusetts, ave invented certain new and useful Improvements in Lens Polishers, of which the following is a specification. I

This invention relates to new and useful improvements in ophthalmic lens polishers, and more particularly to that type. of polisher which is impregnated with wax and abrasive material for carrying out the polishing operation. a

The main object of my invention is the provision of a lens olisher wherein the base or body of the polisher is constructed so as to permit a good portion of the. waxand. abrasive material to become impregnated,

within the body of the polisher so that the polishing surface of the polisher itself will present a smooth and unbroken surface.

'Another object of the invention is the provision of a lens polisher formed of loosely woven material'whereby the particles of abrasive material used for polishing will become impregnated in the meshes of the material forming the polisher so as to present a smooth and unbroken polishing surface.

A further object of the invention is the provision of a lens polisher formed of a woven fabric, .the strands of which are charged with a waxy substance so that when the abrasive material is applied to one 'of the faces of the polisher and the polisher placed in use the particles of abrasive material will adhere to the waxy substance and at the same time be moved into the spaces between the strands, of the fabric whereby through the movement of the polisher over the surface being polished the abrasive material will adhere to all of the exposed surfaces of the fabric and be .moved into the spaces between the strands of the fabric so that a smooth and unbroken polishing surface will be presented to the object being operated upon.

With the above and other objects in View the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings, in which:

Figure I is a plan view of a polisher constructed in accordance with my invention.

Figure II is a transverse sectional view through the same.

Figure III is a similar View illustrating the applicatioin of a waxy substance.

Figure IV is a similar view showing the polisher after the same has been placed in use with the abrasive material applied thereto.

Figure V is an enlarged plan view of a portion of a polisher.

In carrying out my invention I use a fabric preferably of heavy interwoven strands, as illustrated in Figure I, the transverse strands 1 being interlaced with the strands 2 running at right angles to the strands I, so as to provide suitable openings or spaces 3. The individual polishers are cut out in small sections or polishers, as illustrated in Figure I, and the material before being put into use is charged or impregnated with awaxy substance. The material can either be impregnated with the wax before the individual polishers are cut therefrom, or the polishers cut to the desired shape and size and then impregnated waxy substance, as shown at 4, and while the waxy substance is illustrated as a coating for the fabric, it will be understood that considerable of the waxy substance will impregnate the strands of the fabric so that the entire polisher will be fully charged with this waxy substance.

During the polishing of glass surfaces a suitable amount of abrasive is applied to the surfaces of both the polisher and the articles being polished, and as the polisher moves over the surface of the article being polished the, particles of abrasive will readily adhere to the waxy coating 4 of the polisher, and furthermore they will be forced into the spaces 3 between the strands strokes of the polisher upon the surface being operated upon the face of the polisher will present a smooth and unbroken surface and the surface being operated upon will be polished in an etiieient manner.

In a great many instances the polishers which are'being used at the present time for the purpose of polishing glass surfaces, are

'formed with a substantially solid body'jimupon, whereas by the use of aepolishing base 't'ormed'of fabric constructedmt' a plurality of interlaced strands the abrasive matcriat 'Wvliich has heretofore formed in ridges or "lumps will pass intothe spaces between the V interlaced strands so that the face of the polisher, although it Will be understood that the application thereof to one side of the polisher will be sufficient.

In Figure V I have illustrated the'particular construction of the body of the polisher showing how the strands 2 are interlaced with the strands 1, it being understood that the strands 2 extend in pairs at right angles to the strands l and adapted to cross each other between each oi the strands 1 so that each of the two strands running at right angles to the strands 1 will be retained in their proper positions.

As illustrated in Figure V a certain amount of waxy substance has been applied to the strands comprising the polisher so that the polisher is ready for use'and all that is necessary is'the application ot the emery and other abrasive material whcrcb movement of the polishcr over the surface being polished will 'tend to work the particles ot cmcry into the spaces between the various strands going to make up the body of the polisher so that the abrasive material is thoroughly distributed over the surface being polished and also evenly distributed thruoutthe polisher. i

I claim:

A lens polisher con'iprising a fabricbase having cross strands with voids between them, a wax covering the strands but not filling the voids, and a granulated abrasive covering the strands and filling in the voids, held in place by the wax on the. strands.
